WEEDING-IVIACHINE.

SPECIFICATION forming' part of Letters Patent No. 647,828, dated April17, 1900.

Application filed January 4, 190C. Serial No. 350. (No model.)

To a/ZZ whom t may concern:

Be it known that I, FRANK SUMNER GUN- NING, a citizen of the UnitedStates, residing at Dalles, in the county of VVasco and State of Oregon,have invented a new and Improved Weeding-Machine, of which the followingis a full, clear, and exact description.

The objects of the invention are to provide` a simple, light, anddurable machine especially adapted for weeding purposes, means throughwhich the depth to which the weeding-knives shall enter the ground maybe quickly and conveniently determined and controlled, even while themachine is in operation, and means whereby the machine may be instantlyplaced in condition to be drawn to or from a field.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claimsf Reference is to be had to the accompanying drawings,forming a part of this speciiication, in which similar characters ofreference indicate corresponding parts in all the figures.

Figure 1 is an end view ot' the improved machine. Fig. 2 is a plan Viewof the same, parts being in horizontal section. Fig. 3 is an end View ofa portion of the machine, illustrating it in position to be drawn to orfrom a field; and Fig. 4 is a detail View illustrating the manner inwhich a weeding-blade is secured to the frame.

The frame of the machine consists of a front adjustable portion and arear main portion. The front adjustable portion of the frame comprisestwo parallel bars 10 and 11, preferably of angle-iron and placed at apredetermined distance apart, the connection between the two bars beingmade through the medium of connecting-bars 12, three of which are shown,and these connecting-bars are secured rigidly to the rear longitudinalbar 10 and are provided attheir forward ends with sockets 13, throughwhich the forward longitudinal bar 1l is passed and in which socketssaid forward bar 11 iscapable of turning. The end connectingebars 12 areprovided with clevis eX- tensions 14 of any suitable character.

The main portion ot' the frame consists of a central drag-bar 15, havingan attached upper bar 16, upon which the drivers seat 17 is mounted, andside bars 1S, which have a pivotal connection 19 with the rear member 10of the adjustable portion of the frame, as shown in Fig. 2. The sidebars 1S are connected with the drag-bar by means of braces 18L or theirequivalents, and the said side bars 18 are in the form of a yoke andhave secured betweenthem racks 2O and 21, through the medium of suitablecross-bolts 22. Levers 23 and 24: are pivoted between the side portionsof the main frame and the racks 20 and 21, which levers are providedwith thumb-latches adapted for engagement with the racks. The lever 24is connected by a link 25 and an arm 26 with the front bar 11 of theadjustable portion of the frame, thearm being secured to the said frontbar 11, so that this bar may be turned in its sockets as occasion mayrequire. The entire adjustable front portion of the frame, however, maybe raised and lowered through the medium of the second lever 23, whichis connected by a link 27 and an arm -28 with the rear .bar 10 of theadjustable portion ot the frame. Runners 29 are secured to the front bar11 of the adjustable portion of the frame, at or near the ends of saidbars, and these runners are curved, their under faces being convexed,and are usually of thin spring steel or equivalentmetal. Interme diaterunners 30, of stouter material, are sea cured also to the front bar 1lof the adjusts able portion of the frame at each side of the center, asshown in Fig.'2, and these runners determine the depth that theweeding-blades A shall enter the ground, and, furthermore,

serve as forward bearings for the machine when it is to be taken to orfrom the field, as shown in Fig. 3. l

Thus it will be observed that through the medium of the lever 24: therunners may be carried up or down the required distance from the groundand that through the medium of the lever 23 the entire front section ofthe frame may be raised or lowered in such man` sharpened, and likewisean edge of the shank 32. The horizontal sections 31 vof theweeding-blades A are at a right angle to the rear bar of the movablesection of the frame of the machine and incline outwardly in oppositedirections from the center of the said movable section of the frame. Y

The blades are attached to the rear b ar lO of the movable section ofthe frame by means of bolts or their equivalent passed through theshanks of the blades and through brackets 33, which extend downwardlyfrom the rear bar 10, as is shown in detail in Fig. 4. Bracej bars 34are attached to the track-bar l5 of the main frame and are pivotallyconnected with the rear bar of the adjustable section of the frame atveach side of the center ofthe saidrear bar, as is shown particularly inFig. 2. I

the rear portion of the adjustable section of the frame, runners carriedby the forward .portion of the adjustable section of the frame,

a main frame pivotally connected with the .forward adjustable section,and levers carried'by the main frame, having a connection respectivelywith the forward and rear portions of the forward section of the frameofthe machine.

In aWeeding-machine, the combination, with a main frame and leverscarried thereby, of a forward frame, consisting of a rear bar pivotallyconnected with the main frame, and a forward bar adjustably supported bythe rear bar, runners attached to the forward bar of the forward frame,weeding-knives carried by the rear bar of the forward section of theframe, and a connection between one' of the said levers and the forwardbar of the forward section of' the frame and a connection between theother lever and the rear bar of the forward section of the frame,' asdescribed.-

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
